Cell walls of three strains of Streptomyces hygroscopicus previously described as S. hygroscopicus ISP 5578, S. endus ISP 5187, and S. violaceusniger ISP 5563 (= NRRL 1476) contain similar teichoic acids. In each strain, the cell walls contained three structural types of teichoic acids. The major type was a 1,3-poly(glycerophosphate) partially substituted at the glycerol C-2 with alpha-glucosaminyl and alpha-N-acetylglucosaminyl residues. The chains also contained O-acetyl groups. Two minor teichoic acids were unsubstituted 1,3-poly(glycerophosphate) and 2,3-poly(glycerophosphate). The structures were determined by chemical methods and NMR spectroscopy. The possibility to use structural features of teichoic acids as species-specific traits of streptomycetes is discussed.
KEY WORDS: teichoic acids, Streptomyces, NMR spectroscopy, cell wall.
